Below are answers to some of the questions we hear most often from clients.

  • How do I file for divorce in Illinois?

    A divorce begins by filing a Petition for Dissolution of Marriage with the appropriate Illinois court. The filing spouse must meet Illinois residency requirements and properly serve the other party with legal notice of the proceedings.

  • Is Illinois a no-fault divorce state?

    Yes. Illinois is a no-fault divorce state. The only ground for divorce is irreconcilable differences that have caused the irretrievable breakdown of the marriage.

  • How long does a divorce take in Illinois?

    The timeline depends on several factors, including the complexity of the case, whether children are involved, and whether the parties can reach agreements regarding property, support, and parenting issues. Uncontested divorces generally resolve more quickly than contested divorces.

  • What is the difference between contested and uncontested divorce?

    An uncontested divorce occurs when both spouses agree on all major issues. A contested divorce involves disagreements regarding matters such as child custody, property division, or support, requiring additional negotiations or court intervention.

  • Can I get divorced without going to court?

    Many divorce cases can be resolved through mediation, collaborative divorce, or negotiated settlements, minimizing the need for courtroom litigation.

  • What is child custody called in Illinois?

    Illinois uses the term "Allocation of Parental Responsibilities" rather than custody. This includes decision-making responsibilities and parenting time arrangements.

  • How does the court determine parenting arrangements?

    Courts evaluate what arrangement serves the child's best interests. Factors may include the child's needs, parental involvement, living arrangements, and the ability of each parent to support the child's relationship with the other parent.

  • Can parenting plans be modified?

    Yes. Parenting plans may be modified when there has been a substantial change in circumstances that affects the child or family.

  • Can a parent relocate with a child after divorce?

    In many situations, relocation requires notice to the other parent and may require court approval depending on the circumstances and distance involved.

  • What happens if a parent violates a parenting order?

    The court may enforce parenting orders through various legal remedies, including modification proceedings, enforcement actions, or contempt proceedings.

  • How is child support calculated in Illinois?

    Illinois uses an Income Shares Model that considers both parents' incomes, parenting time arrangements, and certain child-related expenses.

  • Can child support be modified?

    Yes. Child support may be modified when there has been a substantial change in circumstances, such as changes in income, parenting time, or the child's needs.

  • What if a parent stops paying child support?

    Legal remedies may include wage garnishment, income withholding orders, contempt proceedings, and other enforcement actions.

  • Does child support automatically end when a child turns 18?

    Not always. Certain circumstances may extend support obligations, including situations involving educational expenses or other court-approved arrangements.

  • What is spousal maintenance?

    Spousal maintenance, commonly called alimony, involves financial support paid by one spouse to another following separation or divorce.

  • How is maintenance determined?

    Courts consider numerous factors, including income, earning capacity, length of marriage, financial needs, and the standard of living established during the marriage.

  • Can maintenance orders be modified?

    In many cases, yes. Modifications may be available when substantial changes in circumstances occur.

  • Does maintenance last forever?

    Not necessarily. The duration depends on the facts of the case, court orders, and any agreements between the parties.

  • How is property divided during divorce in Illinois?

    Illinois follows equitable distribution principles. Marital property is divided fairly, though not necessarily equally, based on the circumstances of the case.

  • What is considered marital property?

    Generally, assets and debts acquired during the marriage are considered marital property, although exceptions may apply.

  • Are retirement accounts divided during divorce?

    Yes. Retirement accounts may be subject to division depending on when contributions were made and other relevant factors.

  • What happens to a family business during divorce?

    Business interests may require valuation and careful analysis before division or settlement negotiations can occur.

  • What is divorce mediation?

    Mediation is a process in which a neutral third party helps spouses negotiate agreements regarding divorce-related issues.

  • Is mediation required?

    Some courts may require mediation for certain family law disputes, particularly those involving parenting matters.

  • What is collaborative divorce?

    Collaborative divorce is a structured process where both parties and their attorneys work together to resolve disputes without litigation.

  • What are the benefits of mediation?

    Benefits may include lower costs, faster resolution, greater privacy, and reduced conflict.

  • Do I need a lawyer for a family law matter?

    While not legally required, experienced legal representation can help protect your rights, avoid costly mistakes, and improve the likelihood of a favorable outcome.

  • What should I bring to my consultation?

    Relevant documents may include financial records, court orders, tax returns, parenting agreements, and any information related to your legal issue.
